top of the bearing 27 and the top of head 18 and between the bottoni of said bearing and the strap 20, the free movement of the 1Irame is provided for as the springs 8 ab- Sorb the movement o' the frame in usual.

mannen yThe steering wheels'l are turned with the head through connections to the steering arm which at its extreme front end has secured thereto a Hang-ed plate 32 to which are attached the two oppositely disposed bars 33 33 having end eyes 34 for engaging the forked ends 35 of the connecting rod 256 which extends transversely between the two steering forks 37 of the knuckle joint 3S.

'l/Vhen the steering connections vfor the Wheels are at the rear of the front axle, the end 25 of the steering arm 25 is utilized for coupling the parts together.

The steering of the vehicle is accomplished by the action of the tongue, and the strain of the pull is transmitted through 'the rear tongue portion 13, which is in reality. the draw bar, to the head 18 and thence to the frame of the yvehicle through the king` pin and its bearings. The iexible connection between the tongue 12 and its draw bar per integree the trailer while the steering is aceompl ished through the tongue attached to the front axle.

What I claim is l. The combination with a trailer vframe including a front axle and an upper trans`v verse metal plate forming an axle bed, a, transverse head brace in the frame and the king pin supported in said brace and bed, of a draw bar and a yoke attached thereto forming a head swiveled on the piu, and a tongue hinged to the drawbar.

Q. The'coinbination with a trailer i'rame and its trans\f'erse head lnracc and a king pin supported therein, of a perforated metallic yoke forming a, head 'and swiveled on the pin, a draw bar attached to the lvolte and a tongue hinged to said bar, a longitudinally arranged'steering arm attached to the head and parallel with the draw bar, and connections therefrom to the steering wheels for turning the wheels in unison with' the movement of the head.

3. The combination with a -trame including the axle, an upper transverse metal plate forming an axle bed and a iiXed bearing plate on said bed, a transverse bearing brace forming part of the trame and a king pin in said plate and bearing brace. or :t metallic `voke forming a head and swiveled `on said pin, a dra-w bar attached to the yoke, a hinged tongueon the bar` a steering arm ixeol to the head, steering wheels and steering forks therefor, and oppositely disposed connecting bars between said arm and forks,
